BOMB-RELEASING SHACKLE.

Application led April 18, 1922. Serial No. 555,404.

To all lwhom t may concern.:

Be it known that we, HERBERT O. RUSSELL and CHARLES LEIGH PAULUs,citizens of the United States, residing, respectively, at Detroit andDayton, in the counties of Wayne and Montgomery, and States of Michiganand Ohio, have invented certain new and useful Improvements inBomb-Releasing Shackles, of whichv the following is a specification.

This invention relates to bomb releasing shackles, the object in viewbeing to provide a shackle especially adapted for releasing and droppingheavy bombs and involving the use of two or more bomb holding' hookswhich are so arranged as to be simultaneously released.

Heretofore with shackles of this character the device for locking andreleasing the hooks has had to sustain the-Weight of the bomb,thus'making the trigger very hard to pull. The present inventioncontemplates making a means for locking and releasing the bomb whichWill'reduce the trigger pull from approximately thirty-eight pounds to.

approximately three pounds.

Vith theabove and other objects in view, the invention consists in thenovel construction, combination and arrangement herein -fully described,illustrated and claimed.

In the accompanying drawings, Figure 1 is a side elevation partly insection of the shackle.

Figure 2 is an end view thereof.

The improved shackle embodies two or more hooks 1 and 2 which areinterconnected so that theywill be simultaneously operable by means of atie rod 3 which is pivotally connected to the hooks as shown.

The trigger 4 has a camming or Wedging .surface 5 adapted to cooperatewith a ca mming or wedging surface on the end of a short link 7 of atoggle mechanism, the link 7 being pivoted at 8. A long toggle link 9 isdisposed in arallelisln with the tie rod 3 when the shac le is locked orset and has one end pivoted at 10 to the tie'rod, theother end` of thelinkr 9 being extended downwardly as shown so as to pass above, beyond,or artiallyaround the pivot 8 of the shortl link, the long link 9 beingconnected by a pivot locked, the Weightl of the bomb tends to turn thehooks 1 and 2 on their pivots. Thisforce is transmitted to the tie rod 3and acts in a longitudinal direction on the latter. `Pull is thereforeexerted on the long toggle link 9. This force acts upon a straightl1ne`pass ing through the ivots 11, 8 and 10, and therefore cannotisturb the position of the trigger. Furthermore the `-leverage is suchthat in springing the end of the toggle link 9 l maintained inengagement with 'the link 7 by means, of a sprlng 14. All of themechanism above described is mounted u on a shackle bar or frame 15adapted to tached to and mounted upon an aircraft.

Having thus described our invention, We iclaim: y
